SHIP LOADING AND UNLOADING SYSTEIII.

Application filed December 5, 1921. Serial No. 519,822.

To all whom it may concern.

Be it known that I, DONALD S. ANDREWS, a citizen'of the United States, resident of Cleveland, county of Ouyahoga, and State of Ohio, have invented new and useful I1n provements in Ship Loading and Unloading Systems, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

This invention relates to systems of loading and unloading ships and has for its object to enable freight to be rapidly transferred'from a car on the pier directly to the ship or vice versa.

The accompanying drawings together with the following description set forth in detail one embodiment of the invention, the disclosed means, however, constituting but one of the various mechanical forms in which the principle of the invention may be employed.

In the annexed drawings:

7 Fig. .1 is a sectional viewshowing, in full lines, the crane removing freight from a box car, and in dotted lines, the crane in. position to lower the freight into the hold of the ship.

Fig. 2 is a similar view showing the crane delivering freight into the hold of the ship.

The pier 1 has a railroad track 2, running longitudinally thereof, on which the boX cars 3 or other types of freight cars may be placed. The pier 1 may be covered by a shed structure 4. Alongside and parallel with the railroad tracks 2 is an overhead crane track 5 upon which is mounted the crane 6 which comprises a mast 7 suspended from the power driven carriage on the track 5 and a vertically adjustable swinging boom 8. The boom 8 carries hoisting tackle 9 and the entire operation of the crane is controlled from the cab 10 mounted to move with the boom. The boom is caused to enter the side door of a car or a the crane track 5. Outside the shed 1 the extension track 10 has a pivoted outer end portion 13 adapted to be folded up out of the way by means of hoisting tackle 1a when not in use, so as not to interfere with the movement of a ship in approaching or leaving the pier, and adapted to be lowered into operative position overhanging a ship 15 after the ship has been positioned for loading or unloading, as shown in full lines in Fig. 1.

In operation the crane 6 is brought along side a box car, the boom 8 is projected into the doorway of the car and a package of freight is engaged by the hoisting tackle 9, lifted clear of the floor, and the crane 6 is then operated to move the boom with its load laterally out of the car doorway. The crane is then moved along the track 5 to the switch section 12 adjacent the ship being loaded and out upon the overhanging track 18 where it is positioned directly over the hatch of the ship. The freight is then lowered into the hold of the ship by means of the tackle 9. The operation in unloading the ship is just the reverse of that described.

As shown inFig. 2 the crane 6 may be employed to transfer freight through a side opening 16 in the ship in the same manner as through the side door of a box car.

What I claim is:

1. In a ship loading and unloading system, the combination with a pier, of an overhead traclt thereon having extensions adapted to project beyond the edge. of the pier and overhang a ship docked at the pier, and a crane suspended on said overhead track and having a vertically movable portion and a boom on said movable portion, whereby the crane may be moved into position over the ship and may be lowered into position opposite a side opening in the ship and said boom may be projected through said side open ing.

2. In a ship loading andv unloading system, the combination. with a pier. of an overhead track thereon having extensions adapted to project beyond the edge of the pier and overhang a ship docked at the pier, and a crane suspended on said overhead track and having -a vertically suspended mast movable over said track and track extensions into position to overhang a ship, and a boom mounted to pivot and move vertically on saidmast and havingtackleon its end, said mast and boom being movable intoposition to dispose the boom opposite a side opening in the .ship and the boom with its tackle being adapted to project into said side opening of the ship for directly placing and removing freight in and from the vessel Without other handling.

3. In a ship loading and iunloading system, the combination with a pier having a railroad track thereon adapted to receive "'frelght cars for transporting freight to and from-a Ship docked at the pier; of an overhead track arranged between the railroad 9 track and the side of the pier, a crane'carriage' on the overhead track, amast dewpending from the carriage, and a boom adjustably mounted on the mast for vertical and horizontalmovement and having tacklethereon for 'engagii'ig freight whereby said carriage and said boom may bead nsted to overhang a ship and may be adjusted to project said boom through the side openings of the ship and a freight car on the pier to directly transfer freight between the ship and'the car Without intermediate handling,

4. In. a shipand freight car loading and unloading system, the co1nbination with a tween ship and shore, ivh-ichconsists in removing the freight from a box car or a Slllllf directly by a suitable mechan1sm, transporting the freight by said mechanism to the box oar or'shipin which the freight is to be I deposited; and finally projecting the same mechan sm through the opening 1n the side of the box ear or the ship to directly position the freight in its final'p'osition in the box car or in the ship, p 4
